All info about our add-ons is available on our website. The website provides a manual (in Google Docs) and links to any relevant video if available. See also the links in the add-on menu to the Help guide. If you are missing anything in the documentation, please let us know and we will fix this.
To help you out on technical challenges with Google Workspace or add-ons, you can get Premium Support. Premium support is one-on-one live technical assistance over mail, phone, or Google Meet. Premium support is offered on a ticket base. Per ticket a fee is requested. You can also request custom development.
